Fix a Leaky Faucet in 30 Minutes

A dripping faucet wastes water. Here’s how to understand the common faucet types and when to stop and call the right pro.

A steady faucet drip often comes down to a worn washer, O-ring or cartridge. If you are comfortable with basic fixture maintenance and your building allows it, the first step is understanding the faucet type and shutting water off safely.

First: Shut Off the Water

Turn the fixture shutoff valves under the sink clockwise. If you cannot reliably shut the water off, stop and contact your building super, landlord or an appropriately licensed plumber. Then open the faucet to release pressure and plug the drain so you don’t lose small parts.

Identify Your Faucet Type

Compression (two separate handles)

An older compression faucet may drip because of a worn rubber washer or O-ring in the stem. Replacement parts need to match the existing fixture.

Cartridge, ball, or ceramic-disc (single handle)

These often use replaceable cartridges or internal seals. The exact disassembly and replacement procedure depends on the manufacturer and model, so follow the fixture instructions rather than forcing parts.

Basic Cartridge-Faucet Workflow

• Confirm the water is fully shut off and the fixture is cool and accessible.
• Remove the handle and trim according to the manufacturer’s instructions.
• Identify the cartridge or service part and match it exactly.
• Reassemble carefully and restore water slowly while checking for leaks.

If It Still Drips

Mineral buildup, damaged seats, corroded fittings or a problem beyond the faucet cartridge can keep a fixture leaking. At that point, stop before creating a larger leak. Building plumbing work or fixture replacement may need the appropriate licensed plumber depending on the scope and building requirements.
